Current Projects

  • Surface modification of aluminum and aluminum alloys with nanoparticles by means of intensity energy flows

    This project aims to obtain modified with nanoparticles of TiCN and AlN layers on aluminum and AlSi12Cu2NiMg alloy substrate by means of selective electron beam melting with increased hardness and wear resistance and clarify the processes of nucleus and structure formation in conditions of rapid crystallization. We plan to study the microstructure and properties of the resulting coatings; optimize of the technological parameters of surface treatment with an intensity energy source; optimize the concentration of nanoparticles in the layers; determine the shape and size of the liquid bath and speed crystallization at selective electron beam melting with a scanning electron beam by methods of numerical modeling; investigate conditions and processes of nucleation and structure formation in introducing nanoparticles in the substrate of aluminum and AlSi12Cu2NiMg; explain the as-obtained layers properties, study the role of nanoparticles with a small and a large difference in the lattice parameters compared to those of the aluminum in the process of rapid crystallization.

    Development of technology for arc overlay welding of wear-resistant layers by introduction of nano-materials in the overlaid metal

    The main objective of the project is development and implementation of innovative technology for arc overlay welding of wear-resistant layers by adding nano-materials to the melt of the weld pool.
  • Mobile systems for critical infrastructure security

    The main goal of the project is developing and improving of advanced security systems based on different types of sensors. In general, the indicative parameters for risk and threat estimation are human heat, movements, vibrations and breaking which induce statics alterations of the system. The sensors which are the most important part of the security systems are based on these principles.

    Adaptive sensory systems based on self-configuring communication-network for environmental parameters analysis

    The project main objective is developing and improving advanced security systems, according to the required security levels of protection, cost and expedience.
  • Improvement of the Urban Security and Defence through the Implementation of Advance Detection Sensors\' System

    In the Europe urban setting provides access to highly integrated infrastructure systems — such as water, electrical and gas supplies; communications; and public transport — as well as to numerous objects such as chemical plants, oil refineries, nuclear plants, etc.

    Development of new lead-free ceramic materials for electronics

    The project is related to the EU policy claiming that from 21.06.2016 the manufactured and imported electric and electronic ceramics should be free of heavy metals. As a member state of EU, Bulgaria is obliged to observe that policy, too.
  • Technical transfer on design documentation, development and optimization of technology for gas counter pressure casting of typical knuckles

    It is developed a complex design and technological documentation of the entire process of production, by a gas counter pressure casting, of a critical part from the suspension of the cars (knuckle).

    Joint Research Program of Nano-modified High Performance Piston Alloy

    It is developed a technology for introduction into the melt of piston aluminum alloy of nanosized powders-modifiers and their assimilation.
  • Research and development of technologies for the recycling of metal scrap

    Due to the increasing amount of metal waste and a mill scale, in particular, there is a need for research of effective technologies for recovery of such waste

    Improvement of the technology for casting of aluminum alloy castings by computer simulation and nanotechnology

    Through computer simulation and introduction of nanomaterials are optimized the casting technologies of different by geometry aluminum castings.
  • Research and determination of optimal technological parameters of electric-resistance welding process of steel wires and reinforcing steel, aiming to increase the quality of the welded joints and reducing of the energy costs

    The main objective is control and management of the electric-resistance welding process of wires and reinforcing steel. This is of great importance for the industry, due to the growing consumption of welded mesh in the building industry, livestock breeding (poultry farming), the commerce and household.

    Investigation of the interaction of silicate systems from an industrial slag with alkali solutions

    The objective of this project is directed towards obtaining new fundamental knowledge on the interaction of a composite glassy phase from pyrometallurgical copper slag with alkaline solutions. The slag has a complex chemical composition, structure, and a strong mineral crystallization ability and the knowledge of the solubility of silica in an alkaline solution and subsequent neutralization with mineral acid cannot be directly applied. The obtained data can be used to create new environmentally friendly processes of recycling slag, and for preparation of micro and nano-size, amorphous silicon dioxide (silica) with low density and large surface area.
  • Utilization of fly ash by-product for production of advanced light-weight low-cost aluminum based composites

    The project can be considered as a complex step in utilization of fly ash by-product trough development of bio-mimetic high-porosity structures and light-weight metallic composites. The main goal is elaboration of technologies for utilization of fly ash generated in China and Bulgaria as reinforce phase in metal matrix composites. Some aluminum alloys will be used as matrix. The obtained composites will be structurally and mechanically characterized and will be analyzed prospects for their application as structural and functional elements.

    New generation light-weight materials for advanced space applications

    The main objective of the project is development, characterization and application of new class of light-weight high performance engineered metallic and metal-matrix composite materials with homogeneous or graded structure. These materials shall provide revolutionary capability, especially for aircraft and spacecraft systems. The specific objective of this proposal is development of porous magnesium alloy reinforced by high strength fibers or metallic wires.
